Description
The present invention relates to a kind of method and apparatus that cleans internal combustion engines, those comprise the method and apparatus that produces power and produce the internal-combustion engine of vehicle powered with diesel oil with gasoline especially to relate to cleaning.
As everyone knows, the workpiece of internal-combustion engine accumulates the residue and the residue of influential engine performance really.The oiling agent of reducing friction in the motor moving element finally can form pollution because of greasy filth, tar and other chemical contaminant that produces (these pollutants are inhaled in oiling agent) in engine working process.Also can occur really wearing away little metal granule, and be carried in the oiling agent from the workpiece of motor.These little metallics can damage the engine components with high-speed and high-temperature work.Thereby the periodic replacement oiling agent is indispensable to the internal-combustion engine of continuous operation, even often change oiling agent, at the still certain productive set of the engine components that include valve, seal arrangement and other operation element pollutant is arranged, these pollutants have then reduced the performance of motor.
Existing in the various prior art systems that are used to clean internal combustion engines and workpiece.These conventional systems have typically adopted a kind of washing fluid that is stored in the storage.This storage is connected on the pump.This motor purging system is provided with one from pump guiding and the import supply lines that comes, and is connected on one of crankcase mouth of equipping on this internal-combustion engine.
In fact, all internal-combustion engines all have an interface and a machine oil oilcan that is used to accommodate dismountable element of oil filter and drain the plug opening.When cleaned engine, oil filter is removed, and the import supply lines that comes from the guiding of washing fluid pump typically is connected on the oil filter interface.Simultaneously, crankcase is drained plug remove, and the washing fluid pumping-out line is connected on the drainage plug hole of crankcase sump.This supply lines and pumping-out line typically are provided with connector, thereby make the leakage minimum of the washing fluid that enters and leave engine body.In case when washing fluid cycled through engine body, it is carried by pump can storage.The conventional purging system of the internal-combustion engine of this typical types is described in, and for example U. S. Patent 1,549, and 952,2,525,978,3,431,145,3,489,245,4,964,373 and 5,063, in No. 896.
In the motor purging system of routine, the cleaning liquid that is adopted is a body of crossing internal-combustion engine along the single direction flushing flow, through filter cleaner and turn back to storage.By means of purge fluid flow is crossed filter cleaner, what it was the trickleest is 3 microns (micron) filter cleaners, and harmful particle can be removed from this washing fluid, so this washing fluid can be used for cleaning nearly 40 internal-combustion engines before it is changed.
If this cleaning solution is used to clean the internal-combustion engine that produces power with gasoline, when reaching the maximum value of 40 this motors along with its cleaning quantity, it will keep its color characteristic to a great extent, and only little by little blackening.Yet if this washing fluid is used to clean the motor that produces power with diesel oil, even harmful matter has been filtered by filter cleaner, it also can become black color immediately.This strong variable color is to cause with the characteristic difference that the burning that generates in the motor with gasoline generation power accumulates thing owing to the burning that generates in the motor with diesel oil generation power accumulates thing.Washing fluid be used for first cleaning the internal-combustion engine that produces power with diesel oil just dyed black, even it is not used to clean any other motor before this.Therefore, although washing fluid can be again clean 40 motors with the remainder of its actual life, it be used to for the first time to clean one when producing the motor of power with diesel oil with regard to blackening, and keep black at the remainder of its actual life always.
Used once when washing fluid, cleaned and be used for cleaning one behind the internal-combustion engine that produces power with diesel oil again when producing the internal-combustion engine of power with gasoline, above-mentioned this characteristic will produce a problem.It is by filter case when washing fluid is discharged from internal-combustion engine, and this housing is transparent typically, so when washing fluid turned back to the storage recovery, it was discharged from internal-combustion engine during cleaning and can see.
The car owner who desires cleaned engine is curious to cleaning process usually and often participates in and watch the motor cleaning process when cleaning.Have the car owner who produces the motor of power with gasoline and cleaned when producing the washing fluid cleaning of motor of power, always notice the washing fluid of black with diesel oil when its car then uses.These automotive vehicle owners that have with gasoline generation power always think that washing fluid has polluted quite severely, the motor car engine that is unsuitable for cleaning them.Consequently, have the automotive vehicle owner who adopts the gasoline driven internal-combustion engine and usually select the motor car engine of no longer going to clean them,, can not clean its motor effectively because they be sure of that washing fluid is too dirty with washing fluid.
Another problem of conventional system for cleaning internal combustion engines is no matter whether this washing fluid is used to clean diesel engine or petrol engine, it is variable color to a certain extent all, also is like this even it just is used to clean several motors and still had quite long actual life.Its result is exactly that except that cleaning former motors, this washing fluid comes out always to be black to a certain degree from internal-combustion engine afterwards.Always think that washing fluid is variable color originally when the automotive vehicle owner sees the washing fluid variable color of discharging in the last moment of cleaning process from its motor, their motor does not clean fully.Therefore they interrogate the validity and the value of this cleaning process.This is unwilling to have cleaned at the motor that carries out from now on regard to causing them.
The invention provides a kind of system, wherein in this system, be used to clean the protected and unlikely rapid variable color of washing fluid part of internal-combustion engine.So just can make to use to produce the internal-combustion engine of power but also capable of washingly produce the internal-combustion engine of power, keep simultaneously seeing outside the washing fluid and present the color of washing fluid that produces the internal-combustion engine of power with gasoline as cleaning with diesel oil with gasoline with a kind of equipment is not only capable of washing.
Equipment of the present invention also has other purposes, cleaned engine more up hill and dale, and not only can keep the color of cleaning liquid but also can prolong its working life in the final stage of cleaning.
According to one aspect of the invention, the device that cleans internal combustion engines has been made improvement, washing fluid is periodically extracted out from storage by a pump in this internal-combustion engine, and flushing flow is crossed internal combustion (IC) engine airframe and by being pumped back to storage.Improvement of the present invention is to provide a pair of washing fluid storage tank and storage tank selector valve device, is used for alternately a fluid storage case being linked to each other with pump, supplying with washing fluid and from wherein reclaiming washing fluid, and cuts off another washing fluid storage tank.
On the other hand, the present invention can think to provide a kind of method of cleaning internal combustion engines.According to this method, oiling agent pumps out from internal-combustion engine, and selects a washer fluid reservoir from paired washer fluid reservoir.Washing fluid is passed through internal-combustion engine with pump pumping from the washer fluid reservoir that chooses.The washing fluid of primary quantity remains in the internal-combustion engine in its whole first soak time interval, discharges then.When the washing fluid of this primary quantity filters when it is discharged, from elimination wherein contaminant particles and reclaiming.For the second time internal-combustion engine is passed through in the washing fluid pumping then.This secondary purge flow scale of construction remains on whole second soak time of process interval in the internal-combustion engine, discharges from internal-combustion engine afterwards.This, amount of washing fluid was filtered second time, to remove contaminant particles and to reclaim.Then oiling agent is put back in the internal-combustion engine again.
In an application of modifying device of the present invention, the washing fluid that is loaded in first storage tank can be exclusively used in the internal-combustion engine of cleaning with gasoline generation power, and the washing fluid in second storage tank can be exclusively used in cleaning produces power with diesel oil internal-combustion engine.Like this, be used to clean the washing fluid that produces the internal-combustion engine of power with gasoline and clean the length of life of whole 40 motors at it, it keeps appearance quality and variable color gradually basically.In fact, even to the end, in order to being exclusively used in washing fluid that cleaning produces the internal-combustion engine of power with gasoline when cleaning the 40th motor, the particular color of this washing fluid keeps to such an extent that to produce the color of the used washing fluid of the internal-combustion engine of power with diesel oil not bad than only cleaning one.
In the Another Application of modifying device of the present invention, an internal-combustion engine can divide two stages to clean.Select the first fluid storage tank by the storage tank selection device, thereby washing fluid is selected at first to pump the case and this motor of flushing in first washing time from this.Closing pump then remains in this first quantitative washing fluid in the motor.This first quantitative washing fluid is used to soak the component of engine interior, and combustion residue was come off in first immersion period.Then this first quantitative washing fluid is discharged and turned back in the storage of selecting for the first time.Before this washing fluid returned first storage, even the washing fluid that comes out from the storage that this is selected for the first time is filtered, but it produced variable color to a certain degree really, and not all pollutant can be filtered by filter in recovery.
The second stage that motor cleans begins by the storage selection device being switched to second storage tank that is selected from paired storage tank.Use the washing fluid from second storage tank to carry out then similar in appearance to the primary flushing second time and the infusion second time.The second quantitative washing fluid that should come from second storage tank returns the storage of selecting for the second time by final infusion then by the filter in the recovery train.Because a large amount of pollutant and residue have been washed from start from starting by the washing fluid that is come by first storage, are relatively unpolluted and relatively non-discoloring so return the washing fluid second time of second storage.Therefore, when the filter of washing fluid from recovery train is back to second storage washing fluid from visually less variable color be clearly, this can be used for flushing and immersion period of final stage.
Because this washing fluid is subjected to less pollution, thereby be to use the life-span to prolong.In addition, when the final variable color that exists really to a certain degree of the washing fluid of second storage, storage tank selector valve device can switch again, thereby the washing fluid that part is polluted in second storage can use in initial flush and impregnation stage.Change the washing fluid in first storage, and the last flushing and the impregnation stage that only it are used in a certain amount of motor are polluted partly until it.This system and then once switch, thereby the order of first and second storages that transposing is selected can be with fresh washing fluid replacements with the washing fluid of the pollution in second storage.
Modifying device of the present invention has made the capacity of conventional internal-combustion engine washing unit increase by one times, and can clean the motor of twice number.If this system is such work, promptly the washing fluid that comes from different storages is used to clean petrol engine and diesel engine, is exclusively used in cleaning so and cleans nearly 40 this motors with the purge flow physical efficiency in the storage of the internal-combustion engine of gasoline generation power.Can clean nearly 40 internal-combustion engines that produce power with diesel oil and be exclusively used in cleaning so that the washing fluid of the internal-combustion engine of diesel oil generation power is same.Because storage separates, thereby washing fluid wherein needn't be changed simultaneously.On the contrary, when being used to clean the washing fluid that produces the motor of power with gasoline and having used to its greatest limit, the main replacing.To produce the washing fluid of motor of power with diesel oil also of no use during to its greatest limit if be exclusively used in, and it can continue to use.
Storage tank selector valve system can be by a simple hand switch control, and this switch provides power to solenoid valve, closes to the passage of another storage tank with the passage that is opened into required storage tank.When continuing to use in the end of a period stage that motor cleans from the washing fluid of a storage tank, this storage tank selector valve also can be between initial flush and impregnation stage and end of a period flushing and impregnation stage switch automatically.
The most preferred embodiment of modifying device of the present invention also has the other desirable characteristics that the conventional engine purging system lacks.Machine of the present invention adopts a motor washing fluid import supply lines that connects from the pump to the internal-combustion engine.In the washing fluid import supply lines of one filter (preferably one 18 microns filter) between pump and internal-combustion engine.This filter is used for protecting client's motor and any residue that was present in washing fluid before arriving motor of filtering.If these residues have been escaped the capture of filter in the recovery train then may have been inhaled in washing fluid.When residue is enough big, may occur on the trickle filter in the recovery train perforation and take back to storage through backflow.
Preferably this system also has a rotatable hose reel that connects between pump and internal-combustion engine.The motor washing fluid drainage tube that the motor washing fluid of one flexibility is supplied with a flexible pipe and a flexibility is contained on this hose reel collapsiblely.Each flexible pipe has a fixing end, and this end is tightened on the radial port of the hollow shaft in the hose reel.This hose reel is separated by a dividing plate inside, so the washing fluid that enters from supply lines keeps separating with the washing fluid of discharging through outlet drainage circuit in motor.
The axial accessory that this outlet supply lines and outlet drop out line route have a slipper seal is connected to the end separately of hollow hoses spool, therein axially accessory to allow relative import supply lines of hose reel and outlet to drain circuit free to rotate, and prevent to produce leakage at this interface place with the hollow hoses spool.Therefore, when washing machine time spent not, flexible pipe can be deposited in the box very compactly, and is that length is enough extracted out in the box and tightened and is connected to car combustion engine oil filter interface and drains on the plug interface, thereby allows washing fluid to circulate through motor.
Washing machine of the present invention preferably also has a filter screen, and it can be 80 micron screen, and the outlet that is placed between internal-combustion engine and the pump is drained in the circuit.This thick filter screen filters big relatively predetermined substance, this predetermined substance be clean out from internal-combustion engine by washing fluid and suck in washing fluid.These predetermined substances, (for example metal fillings) often gone out from internal-combustion engine and sucked in washing fluid.If do not remove before it arrives in the pump as this big predetermined substance, it will produce significantly harm to pump.
The further characteristic of the improved cleaning equipment for engines of the present invention is to be provided with the slightly different filter cleaner of a pair of its hole dimension in the recovery train between pump and storage tank selector valve device.As the filter cleaner of conventional employing paper filter element, device of the present invention does not adopt many carbon (polycarbon) filter cleaner.Be arranged in the aperture that first filter cleaner of the recovery train of close pump has one first specific dimensions, it is no more than 5 microns greatly than the port size of the one second particle filter cleaner in downstream.Preferably the filter cleaner of upstream is one 5 microns a filter cleaner and the filter cleaner in downstream is one 3 microns filter cleaners.
In conventional internal-combustion engine washing unit, have wide-aperture relatively filter cleaner and be arranged in the upstream that the cleaning liquid recycle circuit has the filter cleaner of relative small aperture.For example, in a conventional system, one 20 micron filters are located at the upstream of one 3 microns filter cleaners.Therefore, a large amount of diameter be in particle between the two filter cleaner apertures by upstream filter cleaner and productive set on the filter cleaner of downstream.Consequently trickle downstream filter cleaner stops up rapidly, is back to the recovery rate of storage tank and has lowered the efficient of filtration system in the recovery train thereby reduced washing fluid.
Compare therewith, in system of the present invention, the upstream filter cleaner captures the predetermined substance of much bigger part than elder generation's systematic upstream filter cleaner.Therefore, trickle downstream filter cleaner is not easy to stop up.This has just increased the passing rate of washing fluid and has reduced and cleaned the time that internal-combustion engine is required.After cleaning a different internal-combustion engine, just change and discarded 5 microns thicker filter cleaners.

In case when the washing fluid in the storage tank of selecting reached enough temperature, the thermosensor that links to each other with the heater of selecting just returned to demonstration and working controller 48 by circuit 134 or 136 with signal.This signal in circuit 134 or 136 light be arranged in one link to each other with the storage tank heater remove the lamp of turning on head, thereby indication operator washing fluid has reached sufficiently high use high temperature.
Each storage tank 22 and 24 also is equipped with the liquid level sensor of indicating respectively among the figure at 139 and 141 places.When the liquid level of the washing fluid of the washing fluid storage tank liquid level sensor 139 indication outlets 22 that are used for first storage tank 22 was too low, its just produced a control signal and exports on control wiring 140 so.If a signal in circuit 140, occurs, then in circuit 144, produce a signal and give cycle controller 68 by demonstration and working controller 48.Cycle controller 68 is by the signal at stop air valve 124 in the circuit 126 then, thereby cuts off the power of giving pump 74.This with regard to the washing fluid liquid level in the alert operator storage tank 22 too low and washing fluid should fill again.
Similar liquid level sensor output signal circuit 142 be the liquid level sensor 141 from second storage tank 224 be connected to show and working controller 48 on.If selected storage 24, and if the liquid level of washing fluid drop down onto and be lower than the acceptable limit, then in circuit 142, passed one and output signal to and show and working controller 48.Show then and the control of working 48 provides a signal to cycle controller 68 in circuit 144, thereby this element is turn-offed.Than the time cycle controller 68 by means of the signal at stop air valve 124 in the circuit 126, thereby stop the work of pump 74.Therefore, control wiring 140 and 142 has prevented that storage tank 22 and 24 from producing air pump idle running, so avoided the cleaning of motor 16 insufficient.
Each storage tank 22 and 24 provides independent cycle counter, and this counter has been used for finishing a circulation time increase at storage tank and has once counted.Each storage tank 22 and 24 counter bit are in the working controller spare 48 that shows.Whenever having started the cycle counter that is used for first storage tank 22 after finishing the once flushing circulation, the chosen use of first storage tank 22 and pump 74 once count from the signal increase that cycle controller 68 sends at circuit 146 by one.Similar, whenever second storage tank 24 selected and pump 74 started finish the once flushing circulation after, cycle controller 68 just increases counting by the signal of circuit 148 in the counter that is used for second storage tank 24, the particular count that increases be by in the control wiring 137 from the SC sigmal control that shows and working controller 48 sends, this signal is delivered to cycle controller 68 and storage tank selector valve 34.
Referring to Fig. 3-6 periodic duty of device 10 in a kind of application mode can be described.When in the paired storage tank one be exclusively used in that cleaning produces the internal-combustion engine of power with gasoline and another storage tank is exclusively used in cleaning when producing the internal-combustion engine of power with diesel oil, these illustrate the working state of this washing unit 10.This working state can be by the decision of the state selecting switch on demonstration and the working controller 48.Fig. 3 and 4 is explanation air valves 40, the schematic representation of the working condition of fluid inlet selector valve 52, fluid output selector valve 54 and storage tank selector valve 34.Fig. 3 shows the working condition that is used to clean these valves when producing the internal-combustion engine 16 of power with gasoline when device 10, and Fig. 4 shows the working condition that is used to clean these valves when producing the internal-combustion engine of power with diesel oil when device 10.
The label of air valve 124 " O " illustrate from manage 122 have to pipe that pressurized air is pneumatic 126 and flow during this valve open.Under this condition, compressor 120 is connected, thereby pressurized air is supplied with pneumatic air import 129, so that pump 74 work.Under the opposite condition of being indicated by " C " of closing, compressor 120 cuts off with pneumatic air import 129.Pump 74 is not then worked.
The mark " C " relevant with fluid inlet selector valve 52 illustrates that this valve 52 has been operated, arrives fluid outputs 56 by washing fluid import 62 and flow on the connecting tube 84 on first suction port 76 of receiving pump 74 from washing fluid linking route 67 thereby allow to flow.The mark " O " relevant with fluid inlet selector valve 52 is meant that air is pumped down to the fluid output 56 of import selector valve 52 by air intlet 60 from the top of storage tank 24 by circuit 63.This just allows pump 74 that air is pumped into first fluid dispensing opening 80 from first suction port 76.
The mark " C " relevant with fluid output selector valve 54 illustrates that draining circuit 108 from the outlet of motor washing fluid is free-pouring by outlet valve 54 to fluid the fluid output 58 of second suction port 78 that is connected to pump 74.Under this condition, washing fluid outlet valve 54 pumps that pump 74 can will be drained from the body of internal-combustion engine 16 are to recovery train 128.
When fluid output selector valve 54 is in the condition of being indicated by mark " O ", say from another point of view, be plugged from motor washing fluid outlet drainage the mobile of circuit 108, and pump 74 is by air entry port 64 suctions of circuit 65 and fluid output selector valve 54.Therefore, air distributes outlet 82 by connecting tube 86 pumps to second suction port 78 of pump 74 and by second fluid on it.So just prevented the phenomenon that pump 74 is attempted to vacuumize in the time should not cleaning drainage fluid line 108 pumping washing fluids by motor.The reason of directly not aspirating from surrounding atmosphere from the top pumped air of storage tank 22 and 24 is that this material often is present in these equipment and typically is applied in this class auto repair place for fear of the specific material of suction.
When storage tank selector valve 34 is in the position of mark " C " expression, the supply lines 26 of first storage tank 22 is connected on the import supplying mouth 36 of storage tank selector valve 34 by import accessory 40, and recurrent canal 28 is connected on the import return port 38 of storage tank selector valve 34 by accessory 44.The supplying pipe 30 of second storage tank 24 and recurrent canal 32 are not plugged and are communicated with Anywhere with system.
On the contrary, when storage tank selector valve 34 was in " O " position, the supplying pipe 30 of second storage tank 24 is communicated to supplied with outlet 36, and recurrent canal 32 be communicated to storage tank selector valve 34 return import 38.Under this condition, the supply inlet tube 26 and the recurrent canal 28 of first storage tank 22 are plugged, and do not flow to or flow out this first storage tank 22 thereby do not exist.
For this system is started working, oiling agent is extracted out from motor 16, and the flexible pipe 98 and 102 of hose reel 96 at first is drained.Connector 100 is connected on the engine filter interface 18, and connector 106 is connected on the motor drainage plug opening 20.Begin the work of this system then.
When device 10 is by such state work, promptly storage tank be exclusively used in produce power with gasoline or produce the motor of power and select to go to clean one when producing the internal-combustion engine of power with diesel oil with gasoline, Fig. 5 has illustrated the order of work of valve 124,52,54 and 34 and regularly.When the circulation of Fig. 5 by means of show and working controller 48 on a switch starting time, 180 seconds were opened and be held open to air valve 124.Thereby the work of beginning pump 74, but fluid inlet selector valve 52, fluid output selector valve 54 and storage tank selector valve 34 all are in closed position.Therefore, in case pump 74 is started working, washing fluid passes through the washing fluid import 62 of connecting tube 67 pumps to fluid inlet selector valve 52 through supplying pipe 26 from storage tank 22.From managing 67 washing fluid by valve 52 and connecting tube 84 pumps first suction port 76 to pump 74.Be pumped through from this fluid here and start import supply line 90, at this by filter cleaner 92.The predetermined substance that may damage internal-combustion engine 16 filters in filter cleaner 92.The washing fluid of coming in then enters motor 16 by motor washing fluid input supply lines 98 and by engine filter connection mouth 18.
Because fluid output selector valve 54 is to be in closed condition, therefore, washing fluid to motor washing fluid outlet drop out line 108, passes through filter screen 110 at this this fluid by flushing flow in the engine export drainage tube 102.110 big relatively particles of filtering of this filter screen for example can damage metal fillings or other material of pump 74.Drain the fluid that flows in the circuit 108 in outlet and also include the engine deposits of occlusion in fluid that washed from internal-combustion engine 16 upper punches.
On fluid flows through connecting tube 86 to second suction port 78 that is connected to pump 74 from the washing fluid import 66 of fluid output selector valve 54.Pump 74 forces contaminated washing fluid to distribute outlet 82 by second fluid, and at this, it enters recovery train 128.Most of pollutant in the fluid in recovery train is by filter cleaner 130 and 132 filterings.This filter cleaner 130 and 3 microns of 132 filterings or larger sized material.From the import return port 38 of storage tank selector valve 34, the washing fluid of recovery flow to storage tank 22 by washing fluid recurrent canal 28.
During the major part of whole first time of rinse stage, internal-combustion engine 16 contains the about 1 recirculation washing fluid that adds human relations.After 160 seconds of past, fluid output selector valve 54 is opened, and blocks washing fluid thus and drains circuit 108 and prevent from further to drain washing fluid.This just allows washing fluid in internal-combustion engine 16 quantitatively to rise to about 2 volumes that add human relations.Because outlet fluid selector valve 54 is opened, then air is by managing 65 from the top suction of storage tank 22 and be pumped to second of pump 74 and absorb mouthfuls 78, so avoid forming vacuum at second suction port, 78 places.
Entering circulation during 180 seconds, fluid output selector valve 54 cuts out again, and air valve 124 also cuts out.The interval that this just makes pump 74 quit work for 30 seconds, air valve 124 keeps cutting out always therebetween.During this period, promptly during 180 seconds to 210 seconds, 2 add the quantitative washing fluid of human relations remains in the internal-combustion engine 16, thereby soaks combustion deposit from the internal work parts of motor.
In the time of 210 seconds, air valve 124 is opened again and fluid inlet selector valve 52 is opened to stop from washing fluid import 62 mobile to the fluid output 56 of fluid inlet selector valve 52.Instead, air passes through first suction port 76 of connecting tube 84 pumps to pump 74 from air intlet 60.This just allows air to be pumped to first suction port 76 of pump 74 through air duct 63 from the top of storage tank 24, because, prevent to produce vacuum at first suction port, 76 places.
During 30 seconds between 210 seconds and 240 seconds of work cycle, fluid inlet selector valve 52 is opened.Washing fluid can not enter in the internal-combustion engine 16 by engine filter interface 18, but can get rid of through fluid-evacuation line 102, is back to storage 22 at this fluid flows body selector valve 54 and through recovery train 128.In the time of 240 seconds,, also be few (almost not having) if there is any washing fluid to stay in the internal-combustion engine 16.
In the time of 240 seconds, fluid inlet selector valve 52 cuts out again.Close to 124 moments of air valve, but open again at once.Because fluid output selector valve 54 still keeps cutting out, therefore, washing fluid once circulates again completely from first suction port 76, washing fluid import supply lines 90 and the inlet hose 98 of supply lines 26 through pump 74.During this period, the washing fluid flushing flow is drained circuit 108 and recovery train 128 and is back to storage 22 at internal-combustion engine 16 and through drainage tube 102.
Entering circulation 400 seconds the time, fluid output selector valve 54 is opened again, thereby prevents that washing fluid from further discharging through motor outfall 20.The volume of washing fluid rises to about 2 again and adds human relations in motor 16.In the time of 420 seconds, fluid output selector valve 54 cuts out again and air valve 124 also cuts out.This just makes pump 74 quit work, and pump 74 still keeps static thereby a certain amount of second washing fluid of permission in internal-combustion engine 16 maintains in second soaks at interval.
In the time of 450 seconds, air valve 124 is opened once more, therefore pump 74 is reset.Fluid inlet selector valve 52 is opened, thereby prevents further discharge from storage tank 22 of washing fluid, and flows in the internal-combustion engine 16.Because fluid output selector valve 54 keeps cutting out, washing fluid is then discharged through drainage tube 102, drainage circuit 108 and recovery train 128.Therefore, motor is got rid of washing fluid fully.This second recovery stage and stopped this clean cycle of just being through with.Afterwards, oiling agent is put into internal-combustion engine 16 again, so the automobile of motor after cleaning fully ready for use again.
When an internal-combustion engine 16 with diesel oil generation power is desired to clean, one of valve 124,52 and 54 timing and order and cleaning produce internal-combustion engine identical of power with gasoline, except just fluid output selector valve 54 in whole work cycle, remain and close.This is because there is no need to set up quantitative washing fluid in addition between the circuit soak period in the internal-combustion engine 16 that produces power with diesel oil.When cleaning one when producing the internal-combustion engine of power with diesel oil, storage tank selector valve 34 is held open during whole circulation always, so reclaim through the import return port 38 of supply lines 30 with 36 supplies of outlet supplying mouth and process return line 32 and storage tank selector valve 34 from the purge flow physical efficiency of storage tank 24.
When cleaning produced the internal-combustion engine of power with diesel oil, the washing fluid maintenance in first storage tank 22 separated fully with the fluid in internal-combustion engine 16 or the storage tank 24 and does not have any contact.Therefore, the washing fluid in first storage tank 22 will never with produce the internal combustion engines of power with diesel oil or contact with the washing fluid that is used for this motor.Therefore, keep its color characteristic and can as using the conventional engine washing unit, not clean the internal-combustion engine blackening that produces power with diesel oil at the washing fluid in the storage tank 22 because of operative installations 10.
Fig. 3 to 6 described cleaning equipment for engines 10 when its with this pattern work promptly storage tank be exclusively used in gasoline and produce the motor of power and another storage tank is exclusively used in the working method when producing the motor of power with diesel oil.Yet, the also available different pattern work of cleaning equipment for engines 10 is wherein chosen a washing fluid storage tank and is used for initial pumping washing fluid and reclaims initial quantitative washing fluid and it is back to the washing fluid storage tank of initial selected from a pair of storage tank.Yet in the final stage of cleaning process, another washing fluid storage tank in this a pair of storage tank is selected pumping washing fluid in order, and reclaims a certain amount of second washing fluid by it being back to another washing fluid storage tank.The work timing order of the air valve 124 of this mode of operation, import selector valve 52, outlet selector valve 54 and storage tank selector valve 34 is shown among Fig. 7.As shown in Figure 7, the operator beginning is showing and the order at working controller 48 places by means of producing in circuit 137 that a signal is passed to cycle controller 68.This just makes cycle controller 68 produce a control signal in circuit 126, and produces a control signal at first in circuit 50, thereby opens storage tank selector valve 34.This just causes that cycle controller 68 produces a signal, thus the demonstration that increase links to each other with first storage 22 and the counting of the flush cycle counter in the working controller 48.
Along with pump 74 starts, the storage tank selector valve 34 of washing fluid through cutting out is pumped to fluid output 36 on it from first storage tank 22.From then on, cycle through this system by aforementioned manner, and be back to recovery train 128 through the fluid output selector valve 54 of closing from the washing fluid of first storage tank 22.
Entering circulation in the time of 150 seconds, fluid output selector valve 54 is opened, thereby prevents that the fluid that has polluted from reaching recovery train 128.Therefore, in internal-combustion engine, the washing fluid liquid level is set up the time that kept for 20 seconds.
When 170 seconds, air valve 124 is opened, so pump 74 quits work.Washing fluid no longer cycles through internal-combustion engine 16.But during open at fluid output selector valve 54 20 seconds, the about 2 initial quantitative washing fluids that add human relations of aggregation in internal-combustion engine 16 soak the internal work parts of internal-combustion engine 16.This phase I soaks at interval and lasted till 200 seconds from 170 seconds in circulation.
In the time of 200 seconds, air valve 124 is opened once more, therefore restarts pump.At this moment, import selector valve 34 is also opened, and fluid output selector valve 54 keeps cutting out.This just causes that aggregation all washing fluids in internal-combustion engine 16 are through 128 discharges of outlet drainage circuit.
Entering circulation in the time of 280 seconds, first soak period stops, and all have been drained and be back to same storage tank from the initial quantitative washing fluid of storage tank 22.At this moment, air valve 124 instantaneous closing, but open again at once.Import selector valve 52 cuts out then, and outlet fluid selector valve 54 remains on closed condition.Yet meanwhile, storage tank selector valve 34 is opened, and therefore isolates first storage tank 22 and opens passage in the storage tank selector valve 34 at the circuit Remaining Stages.Selector valve 34 is connected to supplying pipe 30 in the washing fluid outlet 36 and the recurrent canal 32 of second storage tank 24 is connected to and returns in the import 38.Therefore, from the washing fluid of second storage tank 24 second and last rinse stage from 280 seconds to 430 seconds during circulation and recirculation by internal-combustion engine 16.
Therefore in the time of 430 seconds, outlet selector valve 54 is opened, and has stopped washing fluid flows through this system from storage tank 24 circulation.Because fluid inlet selector valve 52 still cuts out, pump 74 is then through fluid selector valve 52 suck purge fluid and it is pumped in the internal-combustion engine 16 from storage tank 24.In internal-combustion engine 16 washing fluid quantitatively rise to about 2 add human relations quantitatively.
Entering circulation in the time of 450 seconds, air valve 124 cuts out, and therefore, pump 74 temporarily quits work.This has just begun second and final impregnation stage, during this period from the washing fluid of second storage tank 24 second soak time at interval in the inner member of powder machine 16 in the immersion.
In the time of 480 seconds, air valve 124 is opened, and fluid inlet selector valve 52 is also opened.Fluid output selector valve 54 keeps cutting out.So washing fluid is discharged from internal-combustion engine 16 and the outlet selector valve 54 through cutting out flow to recovery train 128.Because washing fluid is discharged from motor 16 and supply with washing fluids without first suction port 76 of pump 74, so the washing fluid in the internal-combustion engine 16 all excretes before the circulation finish-time when betiding 595 seconds.Therefore the cleaning of motor 16 finishes, and the oiling agent that cleaning begins to discharge is before put into again.
Cleaning equipment for engines 10 can be worked in such a way, promptly use from the circulation of the washing fluid of first storage tank 22 in circuit first impregnation stage, and second and final flushing use from the washing fluid of second storage tank 24 with impregnation stage and circulate.Clearly the washing fluid in first storage tank 22 pollutes manyly with regard to becoming than the washing fluid in second storage tank 24 when cleaning seldom several motors.
Because the washing fluid in second storage tank 24 keeps untainted relatively state, so the outward appearance of washing fluid has reflected the fact that motor had been cleaned really preferablyly.
After approximately cleaning 40 motors, the washing fluid in first storage tank 22 be replaced and storage tank selector valve 34 reverse.In other words, use in initial flush and impregnation stage, and the fresh washing fluid in first storage tank 22 uses on the contrary second and final flushing and impregnation stage from the fluid of second storage tank 24.
Undoubtedly, a large amount of variation of the present invention and improvement are clearly to those technician that are familiar with internal-combustion engine washing unit and process.Therefore, scope of the present invention can not only be interpreted as that the method that adopted by described embodiment and this paper limits.
